This puzzle-solving process, akin to a plume of computational effort, necessitates significant computational resources, rendering it costly for an attacker to create and maintain multiple fake identities, thereby maintaining the integrity of the network.","stamp":0,"from":"poa15Lw237p7gxFwBF9kGZfqaBsdRXJmQsE1X7CqQ9f1LatA","nonce":2,"parents":["efbfc3829d9ba858f2f6abfceb77c0fa6e4c3ffe23041c147f1b7c5a9f81f822","5170afaa70764424e20c5484da0c99bb9c24821d86473bbec5341b052a1e89b5"],"ts":1792473454,"cid":"poa-mainnet-1","sig":"5Yvco3cW49x6dfzuyQQWhvr6qzwW2tjamCTEzHBthBfgUdAbKMH1MDfHYuSypd89y8JPckAyUZUJGJYquwTXGG9b"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:02:56.724Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
